Q: How many diamond grinding wheels should be used for an alloy bit?: If the hard alloy is generally 100 mesh coarse grinding, and then finishing 180, we have foreign customers dedicated to the electroplating grinding wheel are generally parallel to that, the two particle size. Plain drills and cutters use CBN wheels.

Q: What are the tools, drills, and any of the machine tools made of?: (1) tungsten cobalt carbide, whose code name is YG, consists of CO and wc. Commonly used brand machine tools, bending strong, not afraid of impact, but hardness and heat resistanceIts characteristics are: good toughness, high bending strength, not afraid of impact, but low hardness and heat resistance. Applicable to the processing of cast iron, bronze and other brittle materialsThe commonly used grades are YG3, YG6, YG8 and so on. The latter figures indicate the percentage of cobalt content. The higher the cobalt content, the better the performance of the impact resistance. Therefore, YG8 is often used in rough machining, and YG6 and YG3 are often used in semi finishing and finishing.(2) tungsten titanium carbide, whose code name is YT, consists of WC (tungsten carbide), Tic (Tan Huatai) and CO (cobalt). Commonly used grades are YTl5, YT30 and so on. Its characteristics are: hardness of 89 ~ 93HRA, heat-resistant temperature of 800~1000 degrees; wear resistance and oxidation resistance are higher; but flexural strength and impact toughness are lower. Suitable for processing carbon steel, alloy steel and other plastic materials.Join titanium carbide can increase the wear resistance of the alloy, alloy and plastic materials can improve the bonding temperature, reduce tool wear, can also increase the hardness; but more brittle, poor toughness, performance under impact is also poor, generally used for processing plastic materials. Common brands are YT5, YT15, YT30, digital is behind the percentage content of titanium carbide, titanium carbide content is higher, the red rigid; but the corresponding cobalt content is lower, the worse the more toughness, impact resistance, so YT5 is commonly used in rough machining, YT15 and YT30 are commonly used in semi finishing and finishing processing.

Q: The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?: Put the drill will bite at the top of the hand claw loosen, the drill bit is put into a plug in the end, and tighten with the special wrench, if the old hammer, was struck with an iron wedge bite claw hammer with teeth to tighten the drill.

Q: How about the speed of the drill bit and the feed of the cutter in the machining center?: 1, if I first drill with D13 bit (S600, F80, Q5), and the rest of all milling cutter hole2, casting and steel parts almost turn, the speed can be faster. After 28 of the hole points, use 28 bit S300, F50, Q3. directly3, 35r6 direct spiral down, layer below 0.5-0.8, S1500, F2000-3000

Q: Use an electric drill or hammer installed TV rack?: The TV mounts are all equipped with impact drills which can use 12 impact drills and M8 expansion bolts. Suitable for drilling in cement material hammer, impact drill for existing buildings in non cement material on the wall of borehole.

Q: What brand of drill iron?: The key of the bit selection is not the brand, but the choice of the drill bit.

Q: Drill hammer type matching specifications: Four, five, six pit pit angle shank hammer respectively with four pits, five pits, six angle shank drill.

Q: What do you use for drilling walls?: You want to drill the wall can be used with drill impact drill bit iron. If you don't like the iron hammer can buy the drill bit, the difference between the head with Ukraine ladle head. The head with a shaped yellow color of that. You must push the drill to drill in and you too. Big words can not clamp any drill, below 8 may, if you drill is imported can hold 10mm. Do not go to buy a hammer that bit because it does not fit your electric drill.If you drill is also can be installed if the electric hammer drill, drill the domestic only below 8, imports 10.

Q: What drills do you use for screw holes?: The first drilling, wire tapping in the attack. This depends on how big the screw, then bit than tap.

Q: Grinding the drill bit, how can grinding, and the method of quick crash is what ah?: The edge of the wheel is fixed by the blade." This is the first step between the bit and the grinding wheel. It is often the case that the blade has not been settled so that it is sharpened by the grinding wheel. It must be hard to wear. The "edge" here is the main cutting edge, and the "cut out" means the main cutting edge of the grinding part is in the horizontal position. "Wheel surface" refers to the surface of the grinding wheel. "By" means slowly moving closer. The drill cannot contact the grinding wheel at this time.
